NON-EXPLOSLVELAMP.

SIECIFIGATION forming part of Letters Patent No. 284,353, dated September 4, 1883.

\ i Application filed Jamar-5'23, 1883. (ModeL) Be it known that we, LEOPOLD BA ER THEO- DORE F. MINER, and THEODORETAYLOR, all of La Grande, in the county of Union and State of Oregon, have invented a? new. and Improved Non-Explosive Lamp, of which the following is a full, clear, andexact description. Our invention consists of an improved construction of lamps for burningkerosene and other illuminatingoils, witha receptacle for water or any compound or preparation for cool ing-the oil and preventing the formation of gas, or forextinguishing fire, interposed beobject being to produce a non-explosive lamp of greater efficiency and lower cost than any now inuse, all'as hereinafter fully described. Reference is to be had to the accompanying drawing, forming part of this specificatiomin which the figure is partlya sideelevation and partly. a sectional elevation of :a lamp constructed according to our invention. To the top of the oil-receptacle a, which may be of any form or kind, we propose to "apply a receptacle, 6, for water or any other substance usefulfor: cooling the oil andextinguishing flame, connecting it by a collar, 0, and providing itwith avertical central tube, d, which forms oil and gas tight joints with collar 0 on the top of a, and a collar, 6, at the top of I),

being preferablyblown or otherwise formed in glass, together with the oil-receptacle a, and said receptacle 1) having an orifice, g,;fo1-filling,.and a col1ar,f," with cap or plug of any kind, for closing it, and the collar e at the top being suitably formed for attaching a burner,

into the oil receptacle a. The receptacle b may be made of lighter weight and less strength than. the oil-receptacle, in order that in case the lamp should fall or overturn the receptacle may break and its contents may extinguish the flame at the burner.

Instead of being blown with and perma= nently attached to a, the receptacle b may be,

made separately and *be attached by any approved lamp-collar.

' The tubed being surrounded by the'water or other cooling substancein the receptacle 6 lowers the temperature of the air between the burner and the oil, and thus prevents the aocumulation of explosive gas in the bulb a.

The bulb a can be used either with or without the, filler-cap j, as it can be filled through the tube d. This improved non-explosive attachment can be applied to chandelier-lamps,

head-lights, lanterns, and any other kind of lamps now in use for burning'illuminatingoils. i

Having thus described our invention, we

claim as new and desire to secure by. Letters Patent 1. In an oil-lamp, the combination, with its oil-vessel, of the water or cooling receptacle blown, together with a tube connecting it to the oil vessel or chamber, with the said oil-vessel, the said tube extending through the water or cooling receptacle to provide for the passage of the wick-tube through it, and the said water or cooling receptacle being arranged outside of the oil-vessel, as shown and described. 2. As a new article of manufacture, the oillamp having thewaterf or cooling receptacle blown out of thin glass, together with the oilchamber and a tube, said tube extending through the water-receptacle and connecting the water or cooling receptacle to the oil-chamber, and the said water chamber being arranged outside of the latter, whereby in the event of the overturning or falling of the lamp the .waterreceptacle will break and cause the extinguishment of the flame, as set forth.
